摘要:

基于2017年广州市单体建筑数据,以建筑高度和建筑间距2个指标,确定主城区基本的建筑组合,利用热点分析辨识更高尺度上的建筑组合,在此基础上分析广州建筑组合的空间分布及其影响因素。主要结论有:1)建筑组合有9种基本类型,4 272斑块数量与面积在占比上具有很强的同步性。2)百米尺度斑块构成了主城区建筑组合的基本单元,并以混合用地类型为主,由高层建筑组成的类型用地功能指示作用明显。3)主城区基本类型圈层分布特点突出,各类型圈层分异规律存在差异。4)地价是城市建筑高度、人口密度由中心向外递减的核心制约因子,是城市建筑组合分异的宏观背景因素,并能在平原地形上很好地以圈层形式呈现出来。在百米尺度上,绿地、珠江与主干道在微观层面对建筑组合类型、高度和密度产生影响,使得主城区建筑组合复杂化、多样化。

Abstract:

The study of urban building combinations is necessary to achieve sustainable urban development, as through such a study we can better grasp the process of urban development and evolution, guide the direction of future urban development, optimize the urban ecological environment, and improve urban livability. With the acceleration of China's urbanization process, the development and evolution of building combinations in China's urban areas are also gaining momentum. Therefore, it is of tremendous practical use to explore the laws related to mixed developments in urban areas to guide rational urban planning and the study of urban microclimates. The analysis is an important foundation for the development of urban landscapes and provides important scientific support for the optimization of the urban ecological environment and the improvement of livability levels. From the data on individual buildings in Guangzhou in 2017, this paper determined basic building combinations in the main urban area using two indexes for building height and building spacing, identified building combinations on a wider scale using a hot-spot analysis, and analyzed the spatial distribution of building combinations and the influence of macro and micro factors. Nine building combinations were identified on the basis of average height and spacing of building convergence surface. As the basic units, the nine basic types were further divided into different combinations to form complex and diverse three-dimensional representations of buildings in the main urban area. Building convergence surface with a scale of hundreds of meters constitute the basic unit of building combination in the main urban area, and are dominated by mixed land use types. The basic types, mainly composed of high-rise buildings, played an obvious role in indicating land use with differences in combinations of each functional area. The basic types of main urban areas have prominent circle differentiation, but the laws for the different types differ. Land price was the core constraining factor for the decrease in urban building height and population density from the urban center to the periphery, as well as the background factor related to differences in urban building combinations. The influence of green spaces, the Pearl River, and the main road on the type, height, and density of the building combination at a micro level complicated building combinations.

Key words: building combinations, height, spacing, circle distribution, land price, Guangzhou
